1. XML and XML Web Services
  • XML is a standard for preserving and
    communicating information encoding, tagging,
    and internationalizing that will be everywhere.
  • Web Services provide communication between
    applications running on different Web servers
    that will bring the Internet to its new level.
  • XML Web Services are applications running on
    different devices that communicate XML data using
    XML messages.
  • Interoperable XML Web Services
  • http//www.ws-i.org/Community.aspx

2. EPAs Where You Live
  • Enter your zip code to retrieve environmental
    information about your community
  • Local Emergency Planning Committee (LEPCs)
    provide a forum for emergency management
    agencies, responders, industry and the public to
    work together to understand chemical hazards in
    the community, develop emergency plans in case of
    an accidental release, and always look for ways
    to prevent chemical accidents. Local industries
    must provide information to LEPCs about chemical
    hazards, LEPCs are required by law to make this
    information available to any citizen who requests
    it. You can make a difference by attending an
    LEPC meeting or joining your LEPC.
  • Please Note Currently we have over 3000 listings
    in our LEPC Database. It is our goal to provide
    the most current and accurate information. We
    look to the LEPC community to help us
    successfully meet this goal. Please forward any
    changes or corrections to Dana Robinson. These
    changes will be incorporated and updated monthly.

  • Suggested GSA become a member of FGDC with the
    lead for Locator Services and participate in the
    Open GIS Consortium

5.4.2 Strategy
  • Formed Blue Pages XML Pilot Team from members of
    the VoiceXML Team.
  • Met with GSA Staff and Contractor (SAIC) to
    discuss pilot goals and data needs.
  • Decided on three-pronged approach
  • VoiceXML for ideal Blue Pages database.
  • VoiceXML for current best possible Blue Pages
    database.
  • XML from current sample BluePages database.

39
5.4.2 Strategy
  • CIO Councils Strategic Plan
  • Goal - Interoperable and innovative
    Governmentwide IT initatives.
  • Objective Establish the use of open,
    standards-based architectures.
  • SCOTS Standards-based commercial off-the-shelf
    softwares (XML and XML Web Services).
  • Use XML and VoiceXML for virtual integration and
    updating across the contributing agencies and
    multi-channel distribution (Web, CD-ROM, print,
    telephone, and accessible devices).

40
5.4.2 Strategy
  • A National (INCITS) Standard for directory and
    contact information that supports multi-channel
    dissemination?
  • Phases
  • XML-ization of content (Syndication automatic
    reuse of content on Web sites).
  • Muti-channel dissemination of content.
  • Updating by Web and telephone.
  • Approaches
  • RDBMS to XML direct.
  • Modify/repurpose RDBMS for more optimal XML uses.
  • Define new Markup Language and collect new
    database.

41
5.4.2 Strategy
  • US EPA Pilot Node (Owen Amburs vision)
  • Agency databases e.g. LEPC.
  • Geo-reference e.g. LEPC.
  • Gather and maintain with e-forms e.g. LEPC.
  • Provide access by Web and telephone e.g. LEPC.
  • Include Frequently Asked Questions and Documents
    e.g. Environmental Node on the FedGov Content
    Network.
  • Print XML to PDF - Use new XML Formatting Objects
    (FO) Standard.

42
5.4.2 Strategy
  • Architecture
  • Integrator Node (NXT 3)
  • Agency Nodes (NXT 3)
  • Directory (RDBMS-to-XML Content Adapter)
  • Frequently Asked Questions (Web pages XML
    Index)
  • Frequently Requested Documents (Native file
    formats like PDF, etc. XML Index)
  • State, NGO, etc. Nodes (NXT 3)
  • Same as above.

43
5.4.3 NXT 3 Query for XML
  • Any or all of the fields can be filled in the
    query form.  NXT 3 will take the query, run it,
    and return an XML output to the browser /
    application.  A sample output is attached, but
    you should use the interface (sample_702.xml). 
  • All queries will result in a phone number.  The
    corollary to that is that entries without a phone
    number will not currently appear. 
  • Web site entries associated with agencies
    currently will not be available to the user. 
  • Currently, the number of entries returned is 10. 
    This can be adjusted easily via the form. 
  • As the queries forms are now developed, any
    other blue book database can be added easily, and
    can be queried on multiple servers resulting in a
    single XML return output similar to the one
    returned from the above URL.
